Definition

Noun: - A taxonomic family of marine crustaceans, commonly known as lobsters. In some classification systems, this family is considered coextensive with (or equivalent to) the family Homaridae, which includes the true lobsters like the American and European lobsters.

Usage Notes

• This is a specialized scientific term used primarily in zoology, taxonomy, and marine biology. It is not used in everyday conversation.
• The term specifies a group within the biological classification system (order Decapoda). The note about being "coextensive with the Homaridae" indicates a historical or alternative taxonomic opinion where the two family names refer to the same group of organisms.

Examples

• The commercially important Norway lobster, , belongs to the family Nephropsidae.
• In his research, the biologist studied the morphological differences within the family Nephropsidae.
• Some taxonomic references treat the family Nephropsidae as a synonym for Homaridae.

Advanced Usage

• Taxonomic Context: The usage often involves debate or clarification about classification. For example: "The cladistic analysis supported the separation of the family Nephropsidae from the family Homaridae."

Variants and Related Words

• Nephropsidae: The standard form of the family name.
• Nephropsid (adjective): Relating to or belonging to this family. (e.g., nephropsid species).
• Nephrops (noun): The type genus of this family, containing species like the Norway lobster.

Synonyms

• Homaridae (noun): In the specific contexts where the two families are considered equivalent, this is a direct synonym. However, in other classification systems, Homaridae may be considered a distinct, separate family.

Notes on Meaning

The core meaning is a family of clawed lobsters. The provided definition highlights a key taxonomic nuance: its proposed equivalence to another family (Homaridae). This reflects that biological classification can change as new research emerges.

Noun

1. in some classifications coextensive with the Homaridae
